How does a whale moves?
Whales swim by moving their tail fin and lower body up and down, propelling themselves through vertical movement, while their flippers are mainly used for steering. Some species log out of the water, which may allow them to travel faster. Their skeletal anatomy allows them to be fast swimmers.
Why do humpback whales leap out of the water?
It is an unusual behavior to carry out due to the high-energy demand it requires. For example, a full Humpback breach requires the whale to break through the water’s surface at its top speed of 28km/h. The simplest explanation for a whale jumping out of the water appears to be sociality or alertness.
Do humpback whales travel alone?
Do humpback whales live in social groups? Humpback whales do not live in tight-knit social groups, instead they travel either alone or in transient groupings of two or three individuals (pods) that disband after a few hours, although longer-term associations have been observed.

Has a whale ever saved a human?
